ILLUMINATED TARGET-FINDER.

Specificaton of Letters Patent.

Patented June 20, 1911.

Application filed January 7, 1910. Serial No. 536,939.

T o all whom 'it may concern:

Be it known that I, HERMAN J. HEGWER, a citizen of the United States, residing at Oakland, in the County of Alameda and State of California, have invented certain new and useful Improvements in Illuminated Target-Finders, of which the following` is a. specification.

This invention relates to target illuminating devices for guns, revolvers, and the like, and the principal object of the same is to provide an illuminating device that may be readily Controlled by the user of the firearm so that a ray of light may be projected from the firearm to illuminate the target, the illuminating device being so arranged that its light ray will be projected parallel with the barrel of the firearm thereby permitting the firearm to be centered on the target without the necessity of the user employing the end sight of t-he barrel.

In carrying out the objects of the nvention generally stated above it will be understood, of course, that the essential features thereof, are necessarily susceptible of changes in details and structural arrangements, one preferred and pract-ical embodiment of which is shown in the accompanying drawings, wherein Figure 1 is a view in side elevation of a revolver equipped with the improved target illuminator. Fig. 2 is an end view thereof, the handle and trigger mechanism being omitted. Fig. 3 is a view in side elevation of' the illuminator, the casing thereof being shown in section. Fig. 4-. is a detail view in side elevation of the Circuit Closer for the illuminator. Fig. 5 is a diagrammatic view showing the manner of projecting the light rays from the illuminator.

In the accompanying drawings the improved illuminator has been shown attached to the barrel 1 of a revolver, but it is to be understood, of course, that it is not limited to use in connection with the revolver for it will be obvious that it may be employed in connection with all types of firearms and guns. Said illuminator comprises a cylindrical casing 2 whose ends are open and which is provided .with spring arms 3 adj acent each end that are adapted for firm but detachable engagement with said barrel 1 to suspend the casing from the underside of the barrel, and in the event of the illuminator being used in connection with a revolver that has its cylinder supported upon a shaft 4, the outer end of said shaft may project through the open rear end of the casing 2 as is shown in Fig. 1. A battery 5 is located in the rear end of casing 2 and has a Circuit wire connection 6 with a block 7 carried by the stock of the revolver, said wire extending through said block and having its end nrojected above said post to provide a contact point 8. A concaved reflecting speculum 9 is mounted within the casing 2 in advance of the forward end of battery 5 and is provided with a central opening 10 through which the socket 11 of an incandescent lamp 12 projects, said socket having its contact post 13 in Circuit with the post 14: at the forward end of battery 5. The socket 11 has a Circuit wire 15 extending therefrom that passes through a pendent guide 16 carried by casing 2 and its outer end portion passes through a block 17 carried by the undersurface of the free end of an outstanding spring arm 18 projecting from the stock of the revolver. The portion of wire 15 that passes through block 17 has its end suspended therefrom to provide a contact point 19 that is normally held above conv tact point 8 of wire 6, but which may lie brought into contact with point S to close the Circuit through battery 5 and lamp 12 by pressure applied to the free end of supportino' arm 18 and thereby cause the filament 20 of lamp 12 to glow. The outer end of casing 2 is eXternally threaded as indicated at 21 so that an internally threaded lens collar 22 may be adjustably and detachably fitted thereover. Said collar 22 holds a double ConveX lens 23 in engagement with the outer end of the casing 2.

The filament 20 of lamp 12 may be of the U-shaped shown and it will be seen that when the Circuit is closed through the battery and lamp, the rays from the filament will be concentrated by the speculum 9 and cause them to be directed to the lens 23 and from the lens to converge from the lens to the focal point, as is diagrammatically illustrated in Figs. 3 and 5, and as further suggested by Fig. 5, the light from the illuminator will Cause an inverted image to be thrown on the target that is a refiection of the filament 20, said image being the center of the light and being very bright and surrounded by the usual spot light or halo.

The spring arms that attach the illuminator to the casing 2 are in the form of clips that partially surround the said casing and their arms are so arranged that they may be readily snapped to engagement with the barrel 1.

It will be understood, of course, that in place of the double convexed lens shown in the drawings, two concaVo-convexed lenses may be employed. And also that the distance from the said filament and the mutual center line of the lens is such as to eXactly equal the focal distances of said lens. If the focal distance is shorter, said lens will be necessarily arran'ed closer to the lamp 12 to correspond; i the focal distance is greater the vdistance between the lamp and the lens is increased. To accomplish the necessary adjustment of the lens to Compensate for such differences in the distances, the lens collar 22 may be adjusted through the medium of its threaded connection with casing 2.

Vhat I claim as my invention is A target illuminator comprising a casing,

means carried by said casing for detachably 25 securing the same to the barrel of a gun, a

lens adjustably mounted in the forward end of said casing, a concaved refiector in said caslng, intermedlate 1ts ends, an mcandes cent lamp mounted in said refiector and projecting beyond the same and located from said lens at such a distance as to produce an enlarged inverted image, a batteryT in the rear end of said casing, circuit wires connected to said lamp and battery, a spring Gopies of this patent may be obtained for five cents each, by addressing' the Commissioner of l'atents, Washington, D. 0.
